Thermodynamics CHANGE OF PHASEChange of Phase Summary Classification of PropertiesIntensive properties are independent of mass (temperature,pressure, or any specific property)Extensive properties are a function of the mass of the system(mass, volume) The following terms were defined in this chapter:Saturation - combination of temperature and pressureat which a mixture of vapor and liquidcan exist at equilibriumSubcooled liquid - a liquid at a temperature below saturationtemperature for its pressureSuperheated vapor - a vapor at a temperature above saturationtemperature for its pressureCritical point- the temperature and pressure above whichthere is no distinction between the liquidand vapor phasesTriple point - the temperature and pressure at which allthree phases can exist in equilibriumVapor pressure curve - a graphical representation of therelationship between temperature andpressure at saturated conditionsQuality - the fraction of the total mass ofa mixture that is in the vaporphaseMoisture Content - the fraction of the total mass ofa mixture that is in the liquidphaseRev. 0 Page 39 HT-01
